As will be set forth in detail hereinafter, the addition reaction products of the present invention are especially useful as additives to organic substances and particularly lubricating compositions comprising a major proportion of an oil of lubricating viscosity. With the increased technology in the art of lubrication, there is an ever increasing need for lubricants which will withstand the increasing severity requirements of such oils. While improved lubricants have been developed, it still is necessary to further improve these lubricants and this is accomplished by incorporating one or more additives into the lubricant. The novel addition reaction product of the present invention serves to improve the lubricants in a number of ways including one or more of extreme pres sure (E.P.) additive, oxidation inhibitor, rust and/0r corrosion inhibitor, antiwear agent, viscosity index improver, pour point depressant, etc., and, in addition, serves as a detergent and dispersant. The oxyalkylenated hydroxyhydrocarbon phosphate or thiophosphate and the polymeric condensation product containing basic nitrogen are provided as a unitary product in which the various components, apparently due to close physical and chemical association, co-act to produce an additive of improved properties.

The preferred thiophosphates in this embodiment include di-(oxyethylenated hexanol)- dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated heptanol)-dithiophosphate containing from one to fifteen oxyethylene gorups, di- (oxyethylenated octanol) -dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated nonanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated decanol)- dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated undecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated dodecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated tridecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated tetradecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated pentadecanol)- dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated hexadecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated heptadecanol)dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated octadecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated nonadecanol)-dithiophosphate containing from one to fifteen oxyethylene groups, di-(oxyethylenated eicosanol)- dithiophosphate containing from one to fifteen oxyethylene groups, etc. It is understood that the corresponding mono-oxyalkylenated alkanol dithiophosphate or the corresponding oxyalkylenated alkanol monothiophosphate may be used.

The oxyalkylenated phenol phosphate or oxyalkylenated alkanol phosphate is prepared in any suitable manner. In a preferred embodiment the alkylphenol or alkanol is first oxyalkylenated and then is converted to the phosphate or thiophosphate. Oxyalkylenation of the alkylphenol or alkanol is effected in any suitable manner. In one method this is accomplished by reacting the phenol or alkanol with the alkylene oxide, particularly ethylene oxide, in the molar ratios to produce the oxyalkylenated phenol or alkanol containing the oxyalkylenated group in the desired proportion. The oxyalkylenation generally is conducted at a temperature of from about room temperature to about 350 F. and more particularly from about room temperature to about 200 to about 300 F. When polyoxyalkylenation is desired, the reaction is effected in the presence of a catalyst such as potassium hydroxide, sodium hydroxide, tertiary amine, quaternary hydroxide, etc. When the oxyalkylenation is to be limited to the addition of one oxygroup, the catalyst is used with the al'kanols but may be omitted with the alkylphenols. Superatmospheric pressure may be employed which may range from about 10 to 1000 pounds or more.

The oxyalkylenated aromatic or aliphatic alcohol then is reacted in any suitable manner with P 0 to form the desired phosphate or with P S to form the desired thiophosphate. In preparing the phosphate, one molar proportion of P 0 or other suitable phosphorus oxide is reacted per one or two molar proportions of the oxyalkylenated hydroxyhydrocarbon. In general, an excess of P 0 is employed in order to insure complete reaction. The reaction is effected at a temperature within the range of from about room temperature to about 230 F. and under substantially anhydrous conditions. The resultant free acid form of the phosphate generally is recovered as a viscous liquid.

When the dithiophosphate is prepared, the oxyalkylenated hydroxyhydrocarbon is reacted in any suitable manner with phosphorus pentasulfide or other suitable phosphorus sulfide to form the desired thiophosphate. At

the present time there are different schools of thought as to the structure of phosphorus pentasulfide. It is believed to be P 8 but also has been expressed as P 8 Various structures have been proposed including a polymeric cagelike configuration. Regardless of the exact structure of this compound, phosphorus pentasulfide is available commer cially and is used for reaction with the oxyalkylenated hydroxyhydrocarbon in the manner herein set forth. In the interest of simplicity, phosphorus pentasulfide is also referred to in the present specifications as P S with the understanding that this is intended to cover the phosphorus pentasulfide available commercially or prepared in any suitable manner. The di-(oxyalkylenated hydroxyhydrocarbon)-dithiophosphate is prepared by the reaction of four mole proportions of the oxyalkylenated hydroxyhydrocarbon with one mole proportion of P 8 Generally, an excess of P 5 is used in order to insure complete reaction, which excess usually will not be above about by Weight of the stoichiometric amount of P 8 The reaction conveniently is eifected by heating the oxyalkylenated hydroxyhydrocarbon and, with intimate stirring, adding the P S thereto, preferably in incremental portions. The reaction is effected by refluxing the mixture of reactants to effect formation of the dHoxyalkylenated hydroxyhydrocarbon)-dithiophosphate with the liberation of one mole proportion of hydrogen sulfide.

The reaction preferably is effected in the presence of a solvent and the temperature of refluxing accordingly will depend upon the specific solvent used. Any suitable solvent may be employed. Preferred solvents comprise aromatic hydrocarbons and include particularly benzene. When using benzene as the solvent, the refluxing temperature will be in the order of 175 F. Other aromatic solvents include toluene, xylene, ethyl benzene, cumene, etc., or mixtures thereof. In another embodiment the solvent may comprise a paraflinic hydrocarbon or mixtures thereof which preferably are selected from hexane, heptane, octane, nonane, decane, undecane, dodecane, etc. As hereinbefore set forth, the refluxing temperature will depend upon the particular solvent employed and thus may range from about 140 and preferably should not exceed about 215 F, The reaction may be effected at atmospheric pressure or, when desired, at subatmospheric pressure or superatmospheric pressure.

Hydrogen sulfide is formed in the above reaction and preferably is continuously removed from the reaction zone. After completion of the reaction, the reaction mass may be filtered to remove unreacted P 5 if any. In one embodiment the product may be recovered in solution in the benzene or other solvent or, when desired, the benzene solvent may be removed in any suitable manner such as by distillation, preferably under vacuum. The di-(oxyalkylenated hydroxyhydrocarbon)-dithiophosphate is recovered as a liquid of medium viscosity.

While the di-(oxyalkylenated hydroxyhydrocarbon)- dithiophosphate is a preferred reactant for forming the addition reaction product of the present invention, it is understood that the use of the mono-(oxyalkylenated hydroxyhydrocarbon)-dithiophosphate also is comprised within the scope of the present invention, as well as the monoand/ or di-(oxyalkylenated hydroxyhydrocarbon)- monothiophosphate. The latter compound may be prepared, for example, by reacting di-(oxyalkylenated hydroxyhydrocarbon)-phosphite or the sodium salt thereof with free sulfur.

The oxyalkylenated hydroxyhydrocarbon phosphate or thiophosphate is reacted with a polymeric reaction product containing basic nitrogen to form the novel addition product of the present invention.

In one embodiment, the polymeric reaction product is formed by the reaction of 1) an unsaturated compound having a polymerizable ethylenic linkage and (2) an unsaturated compound having a polymerizable ethylenic linkage and a basic nitrogen.

When desired, the polymerization may be effected in the presence of a solvent and particularly aromatic hydrocarbons as hereinbefore set forth.

In one method, the copolymer is first prepared and then reacted with the amine or alkanolamine or, in another method, one of the monomers is reacted with the amine or alkanolamine and then is reacted with the other monomer. The product will contain basic nitrogen and may comprise esters, amides or mixtures of these. As

The polymeric reaction products containing basic nitrogen specifically set forth in the present specifications may be summarized as being selected from the group consisting of:

1) The reaction product of an unsaturated compound having a polymerizable ethylenic linkage and an unsatu rated compound having a polymerizable ethylenic linkage and basic nitrogen, preferably using from one to four mole proportions of one reactant per one mole proportion of the other reactant;

2) The reaction product of a nitrogen-containing compound selected from the group consisting of an amine containing at least two amine groups and an alkanolamine containing at least one amine and one hydroxyl group, each preferably containing from four and more particularly from six to about fifty carbon atoms, with the condensation product of an unsaturated compound having a polymerizable ethylenic linkage and a compound selected from the grou consisting of polycarboxylic acid, anhydride thereof and ester thereof.

The above description illustrates the polymeric reaction products containing basic nitrogen which are used for forming the addition reaction products of the present invention. In the present specifications and claims, the term basic nitrogen is used in the generic sense to cover the primary, secondary and tertiary amines including, as stated above, the basic nitrogen-containing heterocyclics. It is understood that the different polymeric reaction of condensation products are not necessarily equivalent when used in forming the addition product.

The oxyalkylenated hydroxyhydrocarbon phosphate or thiophosphate generally is reacted with the condensation product containing basic nitrogen in a proportion of from about 0.5 to about 1.0 acidic equivalents of phosphate or thiophosphate per one basic equivalent of condensation product. However, when the condensation product is prepared from an unsaturated acid, the phosphate or thiophosphate may be used in a proportion of phosphate or thiophosphate equivalents which are equal up to the total of both of the basic equivalent and double bonds in the condensation product. In other Words, the thiophosphate preferably forms the addition salt with the basic nitrogen and any excess thiophosphate will add to the double bond in the condensation product. It is understood that applicant is not necessarily limited to the above explanation, but does believe that the reaction proceeds in this manner, and also that a further excess of either reaction may be employed when desired.

The reaction is effected in any suitable manner. The reaction is exothermic and preferably is controlled by effecting the same in the presence of an inert solvent. Any suitable solvent may be employed, an aromatic hydrocarbon being particularly preferred. The aromatic hydrocarbons include benzene, toluene, zylene, ethylbenzene, cumene, etc. Other solvents include saturated aliphatic esters, as ethyl acetate, amyl acetate, Z-ethylhexyl acetate, methyl propionate, methyl butyrate, ethyl butyrate, isopropyl butyrate, etc., saturated aliphatic nitriles as acetonitrile, propionitrile, etc., dioxane, nitrobenzene, chlorobenzene, chloroform, carbon tetrachloride, etc. The specific temperature of operation will depend upon whether a solvent is employed and, when used, upon the particular solvent. In general, the temperature may range from about atmospheric to about 200 F. and in some cases up to 300 F., although temperatures outside of this range may be employed, depending upon the specific reactants and solvents utilized. The time of reaction will range from instantaneous to several hours or more and generally from instantaneous to one hour. Detailed description of specific methods for effecting the reactions are given in the examples appended to the present specifications. The reaction normally readily is effected in the absence of a catalyst.

The addition reaction product generally is recovered as a viscous liquid. It may be marketed and used as such or as a solution in a suitable solvent including, for example, saturated paraflinic hydrocarbons including pentane, hexane, heptane, octane, etc., aromatic hydrocarbons including benzene, toluene, xylene, cumene, decaline, etc., alcohols, ketones, etc. However, when the product is recovered in the absence of a solvent or when the product is not sufliciently soluble in the substrate, the desired solubility may be obtained by dissolving the product in a mutual solvent. Suitable solvents forthis purpose comprise phenols and particularly alkylphenols or polyalkylphenols in which the alkyl group or groups contain from six to twenty carbon atoms. The phenol may be used in a concentration of from about and preferably from about 25% to about 500% by weight and, more particularly, from about 30% to about 200% by weight of the addition reaction product of the present invention.

The addition reaction product of the present invention will have varied utility and is useful as an additive to organic substrates which undergo oxidative deterioration. In addition, the additive serves as a detergent-dispersant, peroxide decomposer, corrosion inhibitor, extreme pressure and lubricity additive, etc. Organic substrates include gasoline, naphtha, kerosene, jet fuel, lubricating oil, diesel fuel, fuel oil, residual oil, drying oil, grease, wax, resin, plastic, rubber, etc.

The mineral oils include those of petroleum origin and are referred to as motor lubricating oil, railroad type lubricat ing oil, marine oil, transformer oil, turbine oil, differential oil, diesel lubricating oil, gear oil, cylinder oil, specialty products oil, etc. Other oils include those of animal, marine or vegetable origin.

The lubricating oils generally have a viscosity within the range of from SUS at 100 F. to 1000 SUS at 210 F. (SAE viscosity numbers include the range from SAE 10 to SAE 160.) The petroleum oils are obtained from parafiinic, naphthenic, asphaltic or mixed base crudes. When highly paraflinic lubricating oils are used, a solubilizing agent also is used.

Synthetic lubricating oils are of varied types including aliphatic esters, polyalkylene oxides, silicones, esters of phosphoric and silicic acids, highly fluorine-substituted hydrocarbons, etc. Of the aliphatic esters, di-(Z-ethylhexyl) sebacate is being used on a comparatively large commercial scale. Other aliphatic esters include dialkyl azelates, dialkyl suberates, dialkyl pimelates, dialky adipates, diakyl glutarates, etc. Specific examples of these esters include dihexyl azelate, di-(Z-ethylhexyl) azelate, di-3,5,5- trimethylhexyl glutarate, di-3,5,5-trimethylpentyl glutarate, di-(Z-ethylhexyl) pimelate, di-(Z-ethylhexyl) adipate, triamyl tricarballylate, pentaerythritol tetracaproate, di-

Additional synthetic lubricating oils include 1) neopentyl glycol esters, in which the ester group contains from three to twelve carbon atoms or more, and particularly neopentyl glycol propionates, neopentyl glycol butyrates, neopentyl glycol caproates, neopentyl glycol caprylates, neopentyl glycol pelargonates, etc., (2) trimethylol alkanes such as trimethylol ethane, trimethylol propane, trimethylol butane, trimethylol pentane, trimethylol hexane, trimethylol hcptane, trimethylol octane, trimethylol decane, trimethylol undecane, trimethylol dodecane, etc., esters and particularly triesters in which the ester portions each contain from three to twelve carbon atoms and may be selected from those hereinbefore specifically set forth in connection with the discussion of the neopentyl glycol esters, (3) complex esters composed of reaction products of trimethylol alkane (as trimethylol propane), pentaerythritol, in fact any dior polyglycol with a dibasic acid, the remaining hydroxyl groups being then esterified with monocarboxylic acids, and (4) tricresylphosphate, trioctylphosphate, trinonylphosphate, tridecylphosphate, as well as mixed aryl and alkyl phosphates, etc.

The present invention also is used in the stabilization of greases made by compositing one or more thickening agents with an oil of natural or synthetic origin. Metal base synthetic greases are further classified as lithium grease, sodium grease, calcium grease, barium grease, strontium grease, aluminum grease, etc. These greases are solid or semi-solid gels and, in general, are prepared by the addition to the lubricating oil of hydrocarbon soluble metal soaps or salts of higher fatty acids as, for example, lithium stearate, calcium stearate, aluminum naphthenate, etc. The grease may contain one or more thickening agents such as silica, carbon black, talc, organic modified bentonite, etc., polyacrylates, amides, polyamides, aryl ureas, methyl N-n-octadecyl terephthalomate, etc. Another type of grease is prepared from oxidized petroleum wax, to which the saponifiable base is combined with the proper amount of the desired saponifying agent, and the resultant mixture is processed to produce a grease. Other types of greases in which the features of the present invention are usable include petroleum greases, whale grease,wool grease, etc., and those made from inedible facts, tallow, butcher's waste, etc.

Oils of lubricating viscosity also are used as transmission fluids, hydraulic fluids, industrial fluids, etc., and the novel features of the present invention are used to further improve the properties of these oils. During such use the lubricity properties of the oil are important. Any suitable lubricating oil which is used for this purpose is improved by incorporating the additive of the present invention.

Oils of lubricating viscosity also are used as cutting oils, rolling oils, soluble oils, drawing compounds, etc. In this application, the oil is used as such or as an emulsion with Water. Here again, it is desired that the oil serves to lubricate the metal parts of saws, knives, blades, rollers, etc., in addition to dissipating the heat created by the contact of the moving metal parts.

Oils of lubricating viscosity also are used as slushing oils. The slushing oils are employed to protect finished or unfinished metal articles during storage or transportation from one area to another. The metal articles may be of any shape or form including steel sheets, plates, panels, coils, bars, etc., which may comprise machine parts, engines, drums, piston rings, light arms, etc., as well as farm machinery, marine equipment, parts for military or other vehicles, household equipment, factory equipment, etc. A coating which may be visible to the eye, or not, as desired, covers the metal part and protects it from corrosion, etc.

The concentration of the addition reaction product to be employed as an additive will depend upon the particular substrate in which it is to be used. In general, the additive is used in a concentration of from about 0.001% to about 25% by weight of substrate and more specifically within the range of from about 0.01 to about by weight of the substrate. When used in conventional lubricating oil, the additive generally may be employed in a concentration of from about 0.01% to about 2% by weight of the oil. When used in lubricating oil for more severe operations, such as hypoid gear oil, the additive is used in a concentration of from about 1% to about or more by weight of the oil. In general, substantially the same range of additive concentration is employed when the oil is used as transmission fluid, hydraulic fluid, industrial fluid, etc. When the oil is used in the formulation of a grease, the additive is used in a concentration of from about 0.5% to 5% by Weight of the oil. When used in cutting oil, rolling oil, soluble oil, drawing compound, etc., the additive may be used in a concentration of from about 0.1% to about 10% by weight of the oil. When used in slushing oil, the additive may be used in a concentration of from about 0.1% to about by weight or more of the oil.

It is understood that the additive of the present invention may be used along with other additives incorporated in the organic substrate. The other additives will depend upon the particular organic substrate. For example, in lubricating oil, the additional additives may comprise one or more of viscosity index improver, pour point depressor, anti-foam additive, detergent, corrosion inhibitor, additional antioxidant, etc. Preferred additional antioxidants are of the phenolic type and include tertiarybutylcatechol, 2,6-ditertiarybutyl-4smethylphenol, 2,4- dimethyl 6 tertiarybutylphenol, etc., 2 tertiarybutyl-4- methoxyphenol, 2-tertiarybutylP4-ethoxypheno1, tetratertiarybutyl-dihydroxyphenyl methane, etc.

Some of the addition reaction products of the present invention are emulsifying agents and therefore will serve to emulsify water and oil of lubricating viscosity for use as lubricating oil, sloshing oil, cutting oil, rolling oil, soluble ,oil, drawing compound, etc. When desired, an additional emulsifying agent may be employed. Any suitable emulsifying agent can be used, including alkali metal sulfonates of petroleum sulfonic acids, mahogany sulfonates, naphthenic acids, fatty acids, etc., fatty alcohol sulfonates, pentaerythritol oleates, laurates, etc. The amount of water used in the emulsified oils will depend upon the particular use of the emulsion and may range from 0.25% to 50% or even up to 98% by weight of the composition.

In another embodiment the reaction products of the present invention possess insecticidal properties with good inner-therapeutic action. They may be employed against many types of mites and insects such as, for example, Corausius larvae, Cotoneaster aphid, apple aphid, black bean aphid, aster aphid, green peach aphid, chrysanthemum aphid, pea aphid, etc. The reaction products or mixture of these may be used for the control of various larvae, mites, eggs of mites and such insects as flour beetle, Mexican bean beetle, black carpet beetle, milkweed bug, German cockroaches, southern army worms, mealy bug, sow bug, citrus red spider, greenhouse red spider, various mosquitoes, yellow fever mosquito, malarial mosquito, houseflies, etc.

The additive of the present invention is incorporated in the substrate in any suitable manner and preferably the mixture is suitably agitated or otherwise mixed in order to obtain intimate admixing of the additive and of the substrate. When the substrate comprises a mixture of two or more components, the additive of the present invention may be commingled with one of the components prior to mixing with the remaining component or components of the substrate.

The following examples are introduced to illustrate further the novelty and utility of the present invention but not with the intention of unduly limiting the same.

EXAMPLE I The addition reaction product of this example was prepared by reacting di-(oxythylenated nonylphenol)-phosphate, containing an average of five oxyethylene groups per each nonylphenyl group, with the polymeric reaction product prepared by reacting maleic anhydride with ethylene. The polymeric reaction product was prepared by dissolving 60 g. of maleic anhydride in 400 g. of toluene and adding 3 g. of benzoyl peroxide. The mixture was sealed into an autoclave and 10 atmospheres of ethylene were charged to the autoclave being heated to 212 F. Following completion of the reaction, the resulting suspension was digested with hot toluene on a steam bath and the product was filtered. A mixture of 42 g. of the above copolymer and 270 g. of N-tallow-1,3-diaminopropane (Duomeen T) was heated and stirred. Gelling occurred at about 212 F. The mixture was heated and stirred to about 258 F., following which 200 g. of xylene were added and the mixture was refluxed at a temperature of about 310 F. A total of 8 cc. of water was collected after 12 hours of refluxing. The polymer had a basic equivalent of 3.29 meq./ g.

The addition reaction product was prepared by commingling with stirring 15.2 g. (0.05 basic equivalent) of the above polymer and 55.85 g. (0.05 acidic equivalent) of di-(oxyethylenated nonylphenol)-phosphate containing an average of five oxyethylene groups. An exothermic reaction ensued. The addition reaction product was recovered as a viscous oil having an index of refraction n of 1.4943.

EXAMPLE II The addition reaction product of this example was prepared by reacting di-(oxyethylenated nonylphenoD-dithiophosphate, containing one oxyethylene group per each nonylphenyl group, with a copolymer prepared by reacting lauryl methacrylate and beta-diethylaminoethyl methacrylate. The copolymer is prepared by copolymerizing lauryl methacrylate and diethylaminoethyl methacrylate in concentrations to yield a product having by weight of lauryl methacrylate and 20% by weight of diethylaminoethyl methacrylate. The polymerization is effected by heating the reactants at about F. for about eighteen hours, with vigorous stirring in the presence of benzoyl peroxide catalyst. The product is recovered as a viscous yellow liquid.

The addition reaction product was prepared by mixing and heating on a steam bath 435 g. (0.1 mole basic equivalent) of the above copolymer and 57.8 g. (0.1 mole acidic equivalent) ,of di-(oxyethylenated nonylphenol)- dithiophosphate containing one oxyethylene group. Here again, an exothermic reaction occurred. The product was recovered as a heavy amber oil having an index of refraction 11 of 1.4816.

EXAMPLE III The addition reaction product of this example was prepared in substantially the same manner described in Example II, except that the dithiophosphate contained an average of six oxyethylene groups per each nonylphenyl group. This reaction was effected by mixing and heating on a steam bath 43.5 g. (0.01 mole basic equivalent) of the lauryl methacrylate-beta-diethylaminoethyl methacrylate polymer, prepared as described in Example II, and 18.64 g. (0.01 acidic equivalent) of di-(oxyethylenated nonylphenol)-dithiophosphate containing an average of six oxyethylene groups. The product was recovered as a heavy amber oil having an index of refraction of n of 1.4848.

As hereinbefore set forth, the addition reaction products of the present invention are of especial utility as additives in lubricating oils. One method of evaluating lubricating oils is by the Falex machine. This procedure is described in detail in a book entitled Lubricant Testing authored by E. G. Ellis and published by Scientific Publications (Great Britain) Limited, 1953, pages 150-154. Briefly, the Falex machine consists of a rotating pin which runs between two V shape bearings which are spring loaded against the pin and provided with means for varying the load. The oil to be tested is poured into a metal trough in which the pin and bearings are partly submerged. The machine was operated for five minutes each at 250 and Distillation range, F. 740*975 Specific gravity at 60 F. 0.8836 Viscosity:

Run No. 4 is a run using another sample of the white oil to which had been added two percent by weight of the 500 pound loads and then forty-five minutes at 750 pound 15 addition reaction product of Example I.

The data collected includes the temperature of the oil at each of the loads and the torque in pounds per square inch at each load, as well as the wear which is determined by a ratchet wheel arrangement in which the teeth are advanced in order to maintain-the desired load. Each tooth is equivalent to approximately 0.000022 inch. Preferred additives are those which impart low temperature, low torque and low wear to the oil.

In another series of tests the machine was operated for five minutes at each load from 250 pounds to seizure at 250 pound increments. The maximum load and the time in minutes at this load to seizure are reported, as well as the temperature of the oil. In this case the higher temperature is preferred because it means that the oil is operating satisfactorily at a higher temperature.

The lubricating oil used in this example is dioctyl sebacate synthetic lubricating oil marketed under the trade name of Plexol 201.

Run No. 1 in the following table is a run made using the Plexol not containing an additive and thus is the blank or control run.

Run No. 2 is a run made using another sample of Plexol to which had been added two percent by weight of the addition reaction product prepared as described Here again, it will be seen that the oil without additive (Run No. 3) underwent seizure at a small load which, in this case was 425 pounds. In contrast, the white oil containing the additive of the present invention did not undergo seizure until a load of 1250 pounds.

EXAMPLE VI The addition reaction product, prepared as described in Example II, is used in a concentration of 0.5% by weight as an additive in grease. The additive is incorporated in a commercial Mid-Continent lubricating oil having an S.A.E. viscosity of 20. Approximately 92% of the lubricating oil then is mixed with approximately 8% by weight of lithium stearate. The mixture is heated to about 450 F., with constant agitation. Subsequently, the grease is cooled, while agitating, to approximately 248 F., and then the grease is further cooled slowly toroom temperature.

The stability of the grease is tested in accordance with ASTM D-942 method, in which method a sample of the grease is placed in a bomb and maintained at a temperature of 248 F. Oxygen is charged to the bomb,

In contrast, the sample of the dioctyl sebacate containing the compound of the present invention (Run No. 2) did not undergo seizure until a load of 1500 pounds. In addition, the oil after evaluation was clear.

EXAMPLE V Another series of evaluations were made in the same manner described in Example IV, except that the lubricating oil was a mineral oil marketed commercially by A. H. Carnes Company as Games 340 White Oil. Ty-pical specifications of this oil include the following:

eight hours. On the other hand, a sample of the grease containing 0.3% by weight of the additive of the present invention will not reach the induction period for more than hours.
